This is a swift call. The swift call has a sound all of its own, due to its a 220 swift case enclosed in wood.  The call is made from cocobolo and it might have some sapwood, which I really like, I think it adds to the call..
The Swift call has been the demise of many coyotes and cats. You can choose 2 voices either the double reed distress or a single reed fawn bleat, the fawn bleat is not only a fantastic coyote call it will also actually call in deer. This is not the exact call you will receive just a representative of it.
. Many have said that this is their go to call
